Collapsible sawbuck



May 15, 1962 R. A. PARSONS COLLAPSIBLE SAWBUCK Filed March 25, 1961United States Patent 3,034,546 COLLAPSIBLE SAWBUQK Raymond A. Parsons,14 South St., Rockport, Mass. Filed Mar. 23, 1961, Ser. No. 97,848Claims. (Cl. 14391) This invention relates to sawbucks of the type whichcan be collapsed for shipment and storage and objects of the inventionare to provide a buck which is inexpensive to manufacture, which isdurable in use, which can be collapsed quickly into very compact form,which has no cross-bar under the log in the path of the saw, which seatsfirmly on the ground without tendency to dig into the ground and whichis adjustable to two operative positions, one aflording teeth forengagement with the log and the other providing smooth surfaces forengagement with the log or other material to be sawed.

According to the present invention the sawbuck comprises a pair ofcrossed legs, the legs of the pairs on opposite sides of the buckforming sets of legs, the legs of each pair being interconnected withpivot pins where they cross, the legs of each of the aforesaid setsbeing interconnected at the bottom with cross-bars which seat on theground throughout the length of the buck, the space between the pivotpins being unobstructed so that a saw may pass through and beyond a logwithout obstruction, and One set of legs being shorter than the other sothat when the buck is collapsed the cross-bar of the shorter set isdisposed over the cross-bar of the longer set. Preferably each of thelegs comprises an angle-iron having right-angle flanges, two flanges ofeach pair being disposed in parallel juxtaposition and the other twoflanges being directed in opposite directions, the cross-bar of the setof longer legs comprising an angle-iron having one flange fast to theaforesaid second two flanges and the other flange extending under theaforesaid first two flanges with a space therebetween to receive thecross-bar of the shorter set. In the preferred embodiment each cross-barcomprises an angle-iron having a side flange fast to the aforesaidsecond two flanges and a bottom flange extending under the aforesaidfirst two flanges, the longer set of legs having a space between saidbottom flange and the aforesaid first tWo flanges to receive the bottomflange of the other cross-bar when the buck is collapsed.

For the purpose of illustration a typical embodiment is shown in theaccompanying drawings in which FIG. 1 is an isometric view adjusted tohave the log held in position with teeth;

FIG. 2 is an end view with the buck adjusted to present smooth surfacesto the log or other material to be sawed;

FIG. 3 is an end view of the buck when collapsed; and

FIG. 4 is a section on line 44 of FIG. 3.

The particular embodiment of the invention chosen for the purpose ofillustration comprises three pairs of legs 1 and 2 pivotallyinterconnected by pivot pins 3. Each leg comprises an angle-iron havingright-angle flanges, one leg of each pair having flanges 4 and 5 and theother leg having flanges 6 and 7. The flanges 4 and 6 are disposed inparallel juxtaposition and are pivotally interconnected by the pins 3,the flanges 5 and 7 extending in opposite directions. Disposed under thebottom of the set of legs on one side of the buck is an angle-ironhaving flanges 8 and 9 and disposed under the set of legs on the otherside of the buck is an angle-iron having flanges 10 and 11. The flange 8is welded to the flanges 7 and the flange 10 is welded to the flanges 5.The flanges 6 may also be welded to the flange 9 but the flanges 4terminate short of the flange 11 to provide spaces 12 for the flange 9when the buck is collapsed, the legs 1 being somewhat shorter than thelegs 2 so that the flange 9 is disposed over the flange 11 when the buckis collapsed. The legs are held against further spreading in extended,operative position by chains 13 or other suitable means which can beunhooked from either the flange 8 or the flange 10 to permit the sets oflegs to be turned about the pivot pins. The flanges 4 and 6 arepreferably provided with teeth 14 to grip a log more firmly.

When it is desired to employ the teeth 14 the buck is set up as shown inFIG. 1 with the apexes of the crossbars directed downwardly. To providesmooth work-engaging surfaces the longer set of legs 1 is swungcounterclockwise (FIG. 2) through approximately 290".

It should be understood that the present disclosure is for the purposeofillustration only and that this invention includes all modifications andequivalents which fall Within the scope of the appended claims.

I claim:

1. A collapsible sawbnck comprising pairs of crossed legs, the legs ofthe pairs on opposite sides of the buck forming sets of legs, the legsof each pair being interconnected with pivot pins where they cross, thelegs of each of said sets being interconnected at the bottom withcross-bars which seat On the ground throughout the length of the buck,the space between said pivot pins being unobstructed so that a saw maypass through and beyond a log, held upon said buck in its operativeposition, without obstruction, and one set of legs being shorter thanthe other set so that when the buck is collapsed the cross-bar of theshorter set is disposed over the crossbar of the longer set.

2. A sawbuck according to claim 1 wherein the crossbar of the set oflonger legs comprises an angle-iron having one flange fast to one sideof the legs and the other flange extending under the legs with a spacetherebetween to receive the cross-bar of the shorter set.

3. A sawbuck according to claim 1 wherein each crossbar comprises anangle-iron having a side flange fast to one side of the legs and abottom flange extending under the legs, and the bottom flange of thelonger set being spaced from the bottom of the legs to provide space forthe bottom flange of the other cross-bar when the buck is collapsed.

4. A sawbuck according to claim 1 wherein each of said legs comprises anangle-iron having right-angle flanges, two flanges of each pair beingdisposed in parallel juxtaposition and the other two flanges beingdirected in opposite directions, the cross-bar of the set of longer legscomprising an angle-iron having one flange fast to said second twoflanges and the other flange extending under said first two flanges witha space therebetween to receive the cross-bar of the shorter set.

5. A sawbuck according to claim 1 wherein each of said legs comprises anangle-iron having right-angle flanges, two flanges of each pair of legsbeing disposed in parallel juxtaposition and the other two flanges beingdirected in opposite directions, each cross-bar comprising an angle-ironhaving a side flange fast to said second two flanges and a bottom flangeextending under said first two flanges, the longer set of legs having aspace between said bottom flange and said first two flanges to receivethe bottom flange of the other cross-bar when the buck is collapsed.
